Sterling Silver 925 Chain Necklace with Thick Heart Lock Charm #1222 Stamped S925 sterling 18 inches long Why I love this piece: Perfect for stacking, mixing and matching. So much personality shines through with this. You can dress it up for going out, or super casual for everyday wear. I'm excited to have added this line of beautiful, yet still very affordable, sterling jewelry to my boutique. A note about the material: A great suggestion was made to me recently how to test if jewelry is, in fact, made of sterling silver as claimed by the manufacturer. This piece does pass the "magnet test" - it shows no magnetic effects. If you have any questions, or if you'd like additional measurements or pictures, just let me know. Thank you for checking out my Poshmark boutique!
